We pay attention to hot forging technology&comma; in order to save the material and CNC machining&comma; improving our hydraulic parts function withstand high pressure situation&period; Here is one application&comma; at the beginning&comma; we developed OEM hydraulic fittings Cross with welding one end connection flange for Doosan construction machinery&comma; this cross will withstand high pressure and vibration&comma; welding area will be not stable and be difficult to control the quality&comma; so we use our forging technology to make it successful as one forged body&period;

The details of high quality control&colon; 60 deg flared cone&comma; thread&comma; and good surface treatment&period;
